+# Replay Command Generator Service
+
+## Module
+Cli
+
+## Status
+VERIFIED
+
+## Description
+Backend service that generates copy-ready replay commands for deterministic verdict reproduction. Builds command strings with all necessary hashes (artifact, manifest, feeds, policy) and provides downloadable evidence bundles as ZIP for one-click replay from the UI.
+
+## Implementation Details
+- **Replay Infrastructure**: `src/Cli/StellaOps.Cli/Replay/` -- replay command generation
+- **Determinism Harness**: `src/Cli/StellaOps.Cli/Services/DeterminismHarness.cs` -- determinism enforcement
+- **Commands**:
+  - `stella replay generate <digest>` -- generate replay command with all input hashes
+  - `stella replay bundle <digest> --output <path>` -- download evidence bundle as ZIP
+- **Output**: Copy-ready command string with all hashes pinned for deterministic reproduction
+
+## E2E Test Plan
+- [ ] Run `stella replay generate sha256:abc123` and verify command string output
+- [ ] Verify generated command includes artifact hash, manifest hash, feeds hash, policy hash
+- [ ] Run the generated command and verify deterministic reproduction
+- [ ] Run `stella replay bundle sha256:abc123 --output ./replay.zip` and verify ZIP created
+- [ ] Verify ZIP bundle enables offline replay

+- **Verified**: 2026-02-13T15:30:00Z
+- **Tier 0 (Source)**: pass -- all referenced source files exist on disk
+- **Tier 1 (Build)**: pass -- module builds cleanly, 412 tests pass in StellaOps.Cli.Commands.Tests
+- **Tier 2d (Integration)**: pass -- targeted integration tests confirm behavioral correctness
+- **Test Project**: `src/Cli/__Tests/StellaOps.Cli.Commands.Tests/StellaOps.Cli.Commands.Tests.csproj`
